Hayward Industrial Products provides instructions for installing 3” - 12” chain operators, part numbers CO1 and CO2. These chainwheels replace handwheels by mounting directly to the geared operator stem, allowing for economical control of overhead valves and ensuring safety and versatility. They are available in cast iron or aluminum.
- Remove the handwheel from the gear operator if it is installed.
- Install the chain wheel onto the gear operator, ensuring proper alignment of cross-pin holes, and then install the cross-pin.
- Thread the chain through the guide-holes in the chain guide, leaving enough slack to fit over the groove in the sprocket rim.
- Attach the assembled chain and chain guide onto the gear-operator hub, ensuring alignment between the guide-holes in the chain guide and the groove in the sprocket rim.
- Follow the enclosed instructions with the chain operator to close the master link.
This document provides a step-by-step guide for the installation of chain operators, emphasizing the importance of alignment and proper assembly to ensure effective operation.
